It’s also capable of dissolving grease thanks to its ability to generate the heat required to melt it and loosen up the debris in your pipes.

What are drain cleaners and how do they work?

Household drain cleaners happen to be chemicals, bacteria, or enzymes which attack organic matter such as hair, food, paper, and fabric, breaking them down so they can be flushed away with ease.

They belong in four main categories based on their components and unique means of clearing up your drains:

  • Acid drain cleaners: Often consisting of common acids such as those of the sulphuric or hydrochloric variety, these products also produce heat which breaks down the debris making it easier to flush it away. However, it’s worth noting most drain cleaners available for domestic use don’t belong in this category since those which do are meant for professional use.
  • Caustic drain cleaners: The main distinguishing feature of drain cleaners in this group is the fact that they’re bases, i.e. they exist at the other end of the chemical spectrum from acids. These cleaners tend to operate by converting any fatty substances blocking your drain into a soap-like substance due to their ability to give off heat. The transformed material is thereby easier to wash away with water, resulting in a cleared drain.
  • Eco-friendly drain cleaners: These products are the only noncorrosive variety of drain cleaners — although care must be taken to protect yourself when applying them in the same way you would with the others. Consisting of enzymes and bacteria, they break down waste such as hair, food, and grease into carbon dioxide, water, and mineral residue which are relatively harmless to the environment.
  • Oxidizing drain cleaners: This last group draws its name from the chemical reaction which occurs when cleaners in this category are poured down a blocked drain: the addition of electrons to the debris. They generally consist of chemicals such as nitrates as well as peroxides.

In this article, we shall be taking a look at ten of the very best drain cleaners as voted for by customers who have purchased these products themselves. We shall also be examining all the features which make them especially effective at getting your drains working perfectly again, ensuring your plans can proceed smoothly without a hitch.

Applying drain cleaners - safety tips

It’s worth noting that caustic and oxidizing drain cleaners, in particular, come with a risk of corrosion to the skin, however, it’s important to act carefully when applying drain cleaners of all kinds. Always read the manufacturer's instructions carefully before applying them and wear thick rubber gloves and eye protection when pouring them down the blocked drain. Avoid using a plunger during their application as this could put you at risk of being splashed by them. You must also keep them out of the reach of children and pets and ventilate the room following their application.


Q: Are there any natural drain cleaning options?

While natural drain cleaners aren’t typically as effective as chemical solutions, there are a few options that might do the trick. Combining baking soda and vinegar causes a chemical reaction to occur that’s been known to help dislodge clogs. By pouring half a cup of baking soda down the drain followed by a cup of vinegar, you’ll cause a chemical reaction. The interaction of baking soda and vinegar causes an acid-based reaction to occur. This is what can help you dislodge your leak. However, it’s really important to note that the chemical process causes a release of carbon dioxide, which is lethal to humans in large amounts. Be sure to rinse the drain after cleaning.

Q: Are the popular drain cleaners safe?

Many drain cleaners use substances that can be toxic to humans and pets. If used in their intended form, you shouldn’t experience any dangerous side effects. But in households where children reside, it’s important to keep your drain cleaners locked up. In order to keep yourself safe while using drain cleaners, make sure to ventilate your space (to eliminate any respiratory infection). And never mix drain cleaners, since doing so can cause harmful chemical reactions. If managed well, drain cleaners can offer a great solution to an icky problem. Be sure to follow the instructions on the label for the best results.

Q: What happens if Drano (or a similar cleaner) doesn’t drain?

The use of Drano (or a similar cleaner) involves a number of chemical reactions. These reactions cause a heat-inducing process to occur. The heat is what helps dislodge clogs in your drains, assisting in the decomposition process at an accelerated rate. When you pour drain cleaners down your pipes, they’ll sit in your clog and repeatedly heat up until released from the pipes. This means that the surrounding PVC will heat up over and over again until the clog is released. In the best case, your clog will dissipate in 15-30 minutes as intended. But if the solution sits in your pipes for an extended amount of time, it can cause permanent damage to your pipes.

Q: Can drain cleaners make a clog worse?

Surprisingly, drain cleaners can actually worsen your clog. What we hope for while using a drain cleaner is to dislodge particles that have congealed in your drain. But drain cleaners can also make your clog into a congealed mass, blocking your pipes further. The best way to manage clogs is by nipping them in the tail before they become problematic. Some people run natural drain cleaners through their pipes on a monthly basis to prevent build ups in their pipes. Chemical drain cleaners are generally most helpful once you’ve already begun to experience a clog that can’t be dislodged by using baking soda and vinegar.

Q: Are drain cleaners bad for your pipes?

Drain cleaners use an acidic approach to dislodging your clog. By default, this means that they can cause damage to plastic and rubber. As long as you follow the directions on the label, your standard drain cleaners shouldn’t cause any long-lasting damage to your pipes. The exception would be if you have a really bad clog and the solution gets stuck in your pipes. If you have a clog that’s preventing any discharge of water, it might be best to consider hiring a professional to fix your clog. Otherwise you risk corrosion to your pipe system (unless your pipes are glass).
